DOOR-SECURER.

SPECIFICATION forming part of Letters Patent N o. 684,000, dated October 8, 1901. Application tiled February 27, 1900. Serial No. 6,677. (No model.)

To OLZZ wtot iv' may cor'web.-

Be it known that I, ANTHONY L. SHORE, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota,- have invented certain new and useful Improvements in Door-Securersg and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved doorsecurer capable of ready application to all kinds of doors for securing the same in such manner that they cannot be opened by manipulating their ordinary locks or door-knobs.

To this end my invention consists of the novel combination of devices hereinafter described, and deined in the claim.

The invention is illustrated in the accompanying drawings, wherein like notations refer to like parts throughout both views.

In said drawings, Figure l is a View in horizontal section illustrating the securer as applied in workin g position, and Fig. 2 is a view of the same parts in elevation from the inside of the room, with some portions shown in section and others broken away.

The door l is shown as provided with an ordinary lock, the knobs of which are marked 2, and the body portion of which is indicated at 3. The lock, of course, is provided with an ordinary lock-bolt 3". The door-frame et has the customary inside casing 4c and outside casing alb. The frame 4: has the usual shouldered recess 4c for limiting the closing movement of the door and is provided with an ordinary latch-plate 5, with suitable passage 5" therein for receiving the door -lock The frame 4 is recessed at 4f.

Having regard to the door securer, I provide a detent-plate a of suitable form for ina sertion between the edge of the door and the :frame 4 when the door is in closed position,

which detent=plate ct is provided With a lug as f or engagement With the latchplate 5 by passing through the opening therein into the recess 4f of the frame 4, as best shown in Fig. l. The plate a is provided with an outwardly-extended screw-threaded stem a,with 5 o which engages a nut g2, carried by a handpiece g4 and having on its inner end an angle-plate b, perforated to pass the stem portion a of the plate a, whereby by manipulating the handpiece g the angle-plate b can be brought into the position shown vin Fig. 1, so that one portion thereof will bear against the door and the other against the inside casing 4 of the frame and be made to tightly lock the parts together by the reaction between the handpiece g and the lug a3 of the plate a when in engagement with the latch-plate 5.

The plate a is shown as provided with a leaf-spring a4 for insuring the engagement of the lug a3 with the latch plate 5 when the portable look is applied in working position.

It is obvious that the door-securer above described is of extremely suitable construction, is capableof application to any door, and that when so applied the door is securely held against opening movement by manipulation of the ordinary lock.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

. A door-securer, comprising a detent-plate having a projecting stem, a passage for the ordinary door-lock bolt, and a detent engageable with one of the passages in the ordinary latch-plate, and a clamping head or knob adjustably securable to the stem of said plate, for cooperation, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
